I remember the dagger and the Bomarc and yes, I am not young.
My Grandparents lived on Key West from the late 50's until they passed. I remember standing on the back patio looking at the huge earthen mound that shielded the one of the many missile battery's on the island. 2 times a day they would elevate/rotate the birds. I always tried to watch through Gramps big (to me at the time) spy glasses. One time I caught a glimpse of a reflection.......It was someone watching me watch them. I was maybe 12.
The birds were hard to distinguish what they were but they were there for Cuba

The Bomarc was a northern tier weapon that was positioned to hit the most likely bomber routes. I believe the furthest south they were deployed was VA. FL was defended with Nike and Hawk missiles. Key West with Hawks only I think and then not until about the Cuban Missile crisis.
Even so, it's probably a good thing that you never wandered over for a closer look...military security folks tend not to have much of a sense of humor.
Might not have been a SAM then...maybe one of these? https://en.wikipedia.org/wiki/MGR-1_Honest_John
You want nimble? Base the aerodynamics on the hummingbird. Try to make a stable airframe turn like a flung lead pipe. That's what the computers do for the lead pipe. Better yet, create a skin that generates vacuum and zero gravity and you can move like a jet pack in space. I'm almost there.....
That will only be achievable with drones. The human body can't withstand that many G's.
